To all whom t may concern.'

Be it known that we, J CHN' D. MORGAN, of Summit7 New Jersey, and LoUis A. HAW- THORNE, of Newark, N. J., citizens of the United Sta-tes, have made Improvementspin Metal-lVoi-king Machines,v of'which the following is a specification.

The invention rela'testo machines for punching' structural shapes and' like work, and incre particularly to machinesf'or traveling and successively vstopping 'the vshape in position to be punched at the desired points, through'the instrumentality of settable and automatically operating distance determining devices, and relates further to novel means and mechanismsfor rapid and precise alternate traveling'and stopping'of the work so that the holes may be'punched therein with great `rapidity and accuracy and at any desired distancesapart from fractions of an inch to many feet.

In the embodied form of traveling or progressingmeans for the work, thebeam w rests upon 'a substantially horizontal lseries of rollers l", which rollers" are driven to progress or travelthev beamwrelatively to the punching mechanism. The rollersl are journaled in bearings 2 upon the machine fra'meB. Fixed tothe shafts of the'ro'llers l arebeveled gears 4, which beveled gears intermesli with corresponding beveled gears 5, which are fiXedu'pon shafts 6.- The shafts 6 are shown dn each side of' the punch mannerby the housing l0;

y In the particular form of progressing meansembodied herein, the beam or shape .r is urged or impelled forward by the rotation* of the rolls 1 and is permitted to so move forward or is restrained from so doing by the' action of af suitable distance determining means, although the invention in many of' its aspects maybe employed with other forms of-beam onshape progressing means. The embodied formof means acting directly to permit and prevent the progressing of the shape a@ land the consequent positioning thereof relative to the tool equipped meanscomprisesa head 1'5 having connections to the distance determining means, the forward-'end of' the beam pressying againstJ the head 15 and thusremaining in consta-nt relation or contact therewith. The headl 15 isattached to a longyhorizon- Work accordingly for punching e these features of tally arranged rail or bar 16 extending backivardly alongside the shape or V'beam w. The distance determining means engages with the rail or bar 16 to accurately position the Work?, relatively to the punching mechanism. The present embodiment of the invention Will be regarded as arranged to operate for feet, inches and siXteenths-of-an-inch.

In accordance Withcertain featuresA of the invention, distance determining devices operating alternately and successively are employed, one such device serving to kposition the shapeffor one'punching, and vthe -other device positioning the shape lfor then'ext successive punching, thus the one device may be setting or set to position the shape While thev other device vis recovering or returning preparatory to its next setting. This vvill save a great dealof time and result 'm an yincrease of speed and aconsequent increase in product. In accordance with certain features ofthe invention suchmechani's'm or means is designed to operate With or be controlled by a distance vrecord sheet or like device, that is, va sheet in which the distance values for successive punchingsfare preliminarily l marked or indicated, the machine recognizing the successive distancevalues so marked and' indicated, and positioningthe In thek embodied form, i v the invention are applied to or included in a distance determining mechanism wherein a member, such as the rail o r bar16, traveling .with the shapeor' beam is provided vvith engagingdevices spaced apart in distances 4equal tothe larger distance values or denominations and an interponentfor stop is `projected into the path .of ,travel of suchengaging" devices at such time as to engage a particular one of said engaging devices to permit of the `right distance or amount of travel of the Work corresponding tothe pari -ticular setting or reading of the distance determining means. Inf connection therewith,I

the lesser *distance values or denominations are supplied or effected the positioning of the Work by varying the position of the interponent along thepathl of travel of the engaging devices.

yIn addition to these features of the invention, other featuresare embodied and real-A e ized, as Will in part be particularly pointed outhereinafter, and all of Which are realized by the means. pointed` out in the ap.- pended claims,.and are exemplified in the embodied form. l

Referring novv more particularly to the embodied vform ,l and considering primarily at this time a single distance determining device,.and. also considering the means. for

4varying the longitudinal position or location of the. interponent alongthe path of travel ofthe engageable member, the rail or bar 16 (see Figs. 1 and is provided on its upper surface with lugs 20 which are a uniform and predetermined distance apart ypreferably one yfoot apart from the engaging face on one lug to the engaging face on the next lug. The bar 16 slides along and is supported by suitable bearings 21 in the machine frame, and it may rest or ride upon lsuitable rollers or other friction reducing bearings (not shown).

Mounted upon the 'machine frame, or otherwise secured in fixed position relatively to the punching means or other i tool equippedv means, is a ixedbearing face 22. Mounted upon suitable supports is a fixed yor supporting shaft 23, shown With its ends bearing on supports 24fand 25. A dovvel pin 26 'keeps the shaft 23v from rotation.

`Rotatably mounted upon the shaft 23 is a cylinder 27 which isvrotatable in proportion or conformity to the desired distance setting, to varyl the longitudinal position of the interponent Which engages the 'selected lug 20 at each distance setting. The left hand end of shaft23 in Fig.l 3is squaredor other- Wise shaped to preserve the'interponent carrier 28 in Verect or fixed position thereon,

While the interponent carrier is slidable longitudinally of the shaft, and mayconvenientlypass through a slot43 in the shaft.

Suitable means are provided 'for causing the interponent carrier to vary its longitudinal position in conformity to the rotation yof the cylinder 27. For this purposefthe left hand end of the cylinder 27 in Fig.' 3 is provided With an inclined or, graduatetd cam face129 against Which the surface 30 of inheld in retracted position bylaspring 32 and as being projectable intoV engaging position by a' solenoid 33 mounted in the interponent carrier 28.v The interponent 31 is connected The Winding of the solenoid is connected by suitable circuits to the settable devices such as al distance record sheet and a'suitable timing mechanism.

Meansy are provided for causing the Ainterponent carrier to follow the cam surface 29 of the positioning cylinder 27, and as embodied, such means comprises a. groove cam 36 on the interior surface of the cylinder 27. Into this groove cam 36 projects a finger 38, which is carried on a rod 39. The rod'39 islongitudinally slidable in an aperture l0l in the interponent carrier28. The

lby a rod 34'vvith the core 35` of the solenoid.

l connection therewith.

rod 89 is acted on by a spring 41, which is'in compression between the interponent carrier and a nut 42 threaded on the rod 39. Thus the interponent carrier will follow the cylinder 27 during'the restoring movement and also during the setting movement and will avoid slamming or loose movement and the consequent shock when the interponent engages the lug for which it is set.

In the embodied formv of means for rotating and stopping the cylinder 27 means are provided which tend to continuously rotate the cylinder, the embodied rform thereof comprising-an annular series .of'gearteeth 50 formed in the outer wall of the cylinder 27. -Meshing with said gear teeth 50 is a pinion 5l, which is loose upon a shaft 52, but having a spring operated friction clutch In the embodied form of clutch connection, the pinion 51 on one side faces upon a collar 53, and upon its opposite side the pinion 5l faces a collar 54 loose upon shaft 52. The collar 54 is acted upon by a spring `55 coiled about shaft 52 and in compression between the collar 54 and a collar 56 fixed on the shaft 52. The shaft 52 is carried in suitable bearings 57 and 58v formed on the supporting pillars or brackets 59 and 60. The shaft 52 has fixed thereto a sprocket wheel 61 over rwhich passes a sprocket chain.` 62 said chain running also over a sprocket wheelr 63 fixed on the shaft of a motor 64.

The embodied form of means for permitting or preventing rotation of the cylinder 27 and setting itv for dierent desired distances includes arcuate grooves 66 formed in the exterior wall of the cylinder 27, and of such length and position as to give or permit the desired amount of rotary movement to the cylinder. Coperating with the respective grooves 66 are corresponding rows or series 67 of pins which are projectable into and retractable from the grooves 66. These pins are automatically` controlled and preferably are controlled by a distance record'. device through suitable means such as corresponding series of solenoids 68. Each of the pins 67 as shown isheld in retracted position byl spring 69, the solenoids 68 when energized acting to set or projectr the corresponding pin into the slot; The solenoids may be in circuitv with'asuitable automatic dist-ance record device 14C-to eEect the successive settings of the cylinder. The initial position ofthe cylinder when it is restored or returned may be effected or determined by a solenoidv operating in the manner described, or in the reverse manner, or by a suitable spring device, or other like means employed for this purpose.

In the embodiedy form a further movement of the cylinder 27 is eifected after the pin 67 representing the-desired distancedenomination, such as one or more inches, has been projected into its corresponding groove 66 and has reached the stopping position at the end of the groove. Such further rot'ation or movement 'is'imparted tol the cylinder 27 to set the interponent for the sixteenthsof-an-inch, and in accordance with onefeature of the invention this is effected by also moving the pin or pins 67 together with the cylinder 27. In the embodied form,` the pins 67 reciprocate in apertures in a plate '80, of partiallycylindrical fornr andt conforming substantially to the surface ofthe cylinder 27. rIhe plate 80 is fixedy to the member 8l, which has aA bearing surface S2, against which bearingl surface the end of the cylinder 27 bears, the member Sl having also a bearing surface 83, which bears on the stationary surface 22. The member 8O lis mounted or journaled on the shaft 23 andl is in fxed'position longitudinally ofthe shaft and has a partial swinging or rotative movement about the shaft. In the embodied form, the pins 67 effect the setting in. inches, and the member' 8l is permitted sufficient swinging movement toy effect the setting* for the additional sixteenths. For the purpose of effecting this setting there are formed in the cylindrical surface. of the member 8l, a series of apertures 85 which are positioned and proportioned to effect the corresponding additional feed for thev sixteenths-of-aninch. Proj eotable into and retractable from the apertures 85 are a series of pins 86, which are impelled retractably byl springs 87, and are projected into their apertures selectively by solenoids 88,-in like or similar manner with the solenoids'68'previously'described. The-pins 86 andir solenoids 88 are carried upon a plate 89 fixed to the support or pillar upon which the bearing surface 62 isborne.

The manner of operation of the device may be'generally stated asfollows:-

The proper solenoid 68 andl the proper solenoid 8S for the desired number of inches and sixteenths having*` been selected* and energized the so-called Z'erofpin or like device will release the cylinder 27, which thereupon will begin to rotate by reason of the driving of pinion 51. l/Vhen the set pin-69 reaches the' end ofl its4 slot inthe corresponding groove 66, the plate SOand pin 69'will then rotate with cylinder 27 to effect the feeding or setting' for the additional sixteenthsover the integral' inch, the member 81 having likewise been released from its detentl and freetomove' for a distance determined by the set pin`86.4 During the rotation of the cylinderv 27, the finger 38 following the caml groove 36 causes the detent carrier.28 toinove longitudinally of shaft 23 a corresponding numberof inches and sixteenths-of-anLinch. The detentI 3l isfthen projected before the proper engaginlg lug 20 .to give the proper number of feet .of travelto the vWork, such projection of the detent 31 being controlled by mechanism later to be described. During the restoring movement of the cylinder127, the member 81 is likewise restored through suitable means suchas'a spring 9,0. .f f f Theform of. meansy which controls the action of the interponent 39 to effect the vsetting .for the. desired number of feet .on shaft 102. `iournaled in a bearing 202 and .in the 'housings 117 and 118; A pinionv108 also on 'sha-ft 102 meshes With external teeth 105 (shown generally in Fig, 1 andindetail in `Figs.v 7, 8 -and 9, and' diagrammatically in -1*1g.f10) comprises settablet'raveling devices having settings 'representing feet, such devices traveling proportionatelyV toy the travel of `theshape m.. Asl embodied, arack 100 is formed uponthe rail 161vith Whichvrack lmeshes a `pinion '101, said pinionbeingfixed Shaft 102 is conveniently on an internally and externally geared ring 104. Internal teeth 106 on said gear ring 104 mesh with a pinion 107 fixed on a shaft 108 Which shaft 108 is carried on. an arm 113, which arm yissupported` on bushing 125 and on. .shaft 102. A gear 109 isziixed on the opposite end of shaft 108, said gear meshing With teeth 110 on the hub of ,a disk4 111.

The disk 111, gear 104 .and disk 126 are ro-v ,tatively mounted on, Vbut electrically insulated. from shaft 144 by a bushingy 115. Shaft 144 is fixed in the housing 117 andv118. The housing 117 carries tenl contact plungers v Ior. pins 119, mountedi'n insulated 4bushings 120. v On' theinsulating bushings 120 are a series of open contacts 220, which are closed by enlargements. 221 on the` plungers 120 (see Figs. 7 .and `10) lThe plungers vor pins 119 are equally spaced circumferentially around ythe face ofl housing 117, theinter- 'but having electrical Contact With a disk 122, which disk -is xed to a sleeve. 124. The sleeve 124 is internally insulated from shaft 114 by the bushing 115, and is externally insulated 'from Adisk 111, and from arm 113,

gear104 and disk 112 by a bushing 125. The disk 112 carries a copper segment 127 insulated from the disk and electrically connected With a disk 126, Which disk is fixed to the sleeve I124.v Contact plungers or pins 128 yare vmounted in insulating bushings 129,

carried in housing 118. On the insulating' bushings 129 are a series of open contacts 229, which are closed by 'enlargements228 on the plungers'128 y(see Figs. 7 and 10). Said pins v128 are actuated and controlled by solenoids 162.' The Contact plungers 128 are equally spaced circumferentially on the facev of the housing 118, the intervening spaces representing tens of feet ofv travel of the rack 100. Y- The manner of operation of the foregoin mechanism in recording or setting the required distanceforfthe feet and tens of feet part of the distance, soas to project the interponent '31 into engaging position with the proper lug 20, is substantially-as'follovvs:-

`Suppose a vdistance of thirty-three feet is `to-be traveled or measured before the circuit is closedto project the interponent 31. The key or pin of the series 119 vvhich corresponds to the numerical value of 3, and the key or pinof the series 128, which corre- 1 circuit connections are made to energize the corresponding solenoid of the series 121 to set the three foot lcontact vkey or pin of the series 119 and the corresponding l solenoid of the series 12,8 which sets the thirty foot key or plunger 129. The closing of the contacts'220 andu229 corresponding .to the set .plungers 119 and 128, respectively, energizes the contact points carried by these respecvtive plungers, in position to .complete the circuit when the contact points on. both set plungers 119 and 128 simultaneously are in contact With their respective..rotating segments 123 and y127. The timery is thus set and as the bar travels forward, the

pinion 101 rotates therewith.l The movement is transmitted therefrom to the gearing already described,rotating disk 111 one revolution for each ten feet of travel of bar .or rack 100,.and rotating disk112 one revolution for each one hundred feet of rack travel.

Disk 111 Will make contact between its coppersegment 123 and the three foot set.

segment 127 electricallyconnected in series With the disk111, and disk 112 Willclose the circuit. when the rack 100 has traveled thirty feet.y There is a gaphovvever in the circuit at the,y disk 111'until the three foot contact closes this gap, and thus the tWo gaps in the circuit are only "closed at thirtythree feet. of travel ofthe rac-k 100. At this juncture, the circuit being complete, the solenoid 33 is energized, and the interponent 31 yis projected into the ypath .of the proper n contact lug 20. vThe inches and fractions of an inch of the distance is conti'olled by the longitudinal movement of the interponent carrier 28 as already described. Thus the complete setting for the entire distance is effected, and the shape properly and accurately positioned to'be punched.

In accordance with certain features of the invention, as already indicated, a plurality of distance determining devices are alternately operated, and such arrangement is shown in Figs. 1 and 6 of the drawings and diagrammatically in Fig. 10 although it will be understood that the invention in lmany of its aspects is applicable toa single distance determining device operating alone, `or a plurality of such devices operating together.

In the embodied form of plural or alternate operation, each mechanism may be substantially alike, so far as its principal features of construction and operation are concerned. In the two devices shown, the cylinders 27 are shown oppositely disposed, as will be clear from Figs. 1 and 6, whereby with the use of one common drive therefor, one cylinder can be making a setting while the other is restoring for a succeeding set` ting, the consequent over-lapping of the times in the cycle operation of the respective devices, effecting a great saving of time and consequent increase of product. y In accordance with one feature of the invention, means are provided whereby the controlling circuit for two distance determining devices are successively cut in and cut out so that upon successive settings only one series of solenoids or'other controlling devices is energized or set while the other device is restoring preparatory for a new setting. In Fig. 10 of the drawings a distance record sheet`140 is shown having cooperating 4sets of contacts 141, 142 which are permitted to close their respective circuits by the occurrence ofproperly located perforations in the sheet 140 v(the contacts being held apart by the sheet and the circuits remaining open when the perforations do not occur). Thus by the automatic feed of the distance record sheet the successive distance settings are effected. In Fig. 10 there is also shown a diagrammatic layout of one form of circuit wiring or arrangement suitable for the machine, although so far as concerns many features of the invention, any suitable arrangement or system of wiring may be employed. `The timer dials a and aa represent the dials in the machine for the feet and tens of feet, and showing for each of the dials one. of the solenoid operated Contact plungers marked respectively by reference numerals 121 and 162. Z), c represent the inches and sixteeuths-of-an-inch, respectively, of one of the distance determining devices, one .of the .-solenoids 68 and one of the solenoids 88 being shown cooperating therewith. The inch and siXteenth-of-an-inch controls of the other or alternate distance determining device are indicated respectively as and c, and one each ofthe corresponding solenoids are indicated respectively as 68 and 88. switches which may be of the ordinary relay type. f and g represent the interponents of the two distance controlling devices, which are marked 31 in the drawings of the mechanism, and which engage with the lugs on the rail 16. M represents the motor which drives the distance determining mechanisms, and which is marked 64 in the drawings of the machine. s represents -a four arm, double throw switch, and B and B2 represent` sources of electric current for the various circuits.

Let it be assumed by way lof example,

vthat the distance recordsheet 140 presents to the contacts perforations for a feed of the work amounting to twenty-one feet, three and live siXteentlis inches, and that the various contacts, solenoids and stop pins shown are those corresponding to such reading, The two distance determining devices being oppositely constructed as heretofore explained, one will be restoring preparatory to being` reset, while the other of said devices is advancing to a setting. On ithe next feed of the machine, and with the arrangements showinthe motor M is reversed, and the contrary conditions obtain, respectively, as to the setting and restoring of the distance. determining devices.

The perforations in the sheet 140 permitting the circuits to close, and considerving the closed contacts from the left'hand toward the right, current from the source B flows through the first closed contact into the timer solenoid rm: which sets the requisite solenoid for the tens of feet, namely the twenty solenoid, thecurrent returning through the solenoid to source B. Considering now the second contact from the left4 on the sheet 140, the closingof this contact causes the current to flow through and energize the solenoid cooperating with disks a for the proper units of feet,

` namely the one; The circuit returns from the solenoid to the source B. The third contact allows the current to pass to the corresponding solenoid y68 and 68 toy set c and c for theV threel inch stop pins of both devices, the circuit continuing to the ,opposite terminals of the 'switch s, shown at the right hand side of the switch in Fig. 10.

Assuming the switch s to be closed below and open above, the solenoid 68 of the device c, which connects to the upper switch termi- (l and e' represent electro-magnetic ice n nal will carry no current on account of the switch being open, and, therefore, thev solecorresponding distance pin be set.

When vthe timer reaches the point where the twenty foot contact and the. one footy contact are closed simultaneously, asl already described in connection with the mechanism, a pathKVV is provided for the current to bothuof the interponent solenoids 7, and g. The negative sides of the solenoids are wired to opposite terminals of the switch e, the solenoid f being connected to the upper `terminal is inoperative, under the setting of the switch previously assumed, while the solenoid g,

connected" to the lower terminal of switch s, completes its circuit through s and back to the source of energy. The setting of the A linterponent g closes the relay circuit controlling yswitch 7L and thereby allows current to flow through the coils of relay e. Relay e closesthe circuit through switch s at the lower contact to start the driving moa tor for thedistance determining devices and l switch S.

Thus therey is alternate u operation or setting of the-,two distance determining devices, effected automatically by' the machine itself, when the switch 8 `is mechanicallyoperated as described.: lt willbey understood that the motor M will have suitable windings for the particular kind of work as will kbe clearly understood bythose skilled in the art. f

So far as concerns the. location of the timer'k interponents longitudinally of the rail 16, they have been shown one after the the other and arranged in the saine direction. It will be clear, however, that they could be arranged in'various ways, as. for

instance, one of them` could be turned ,end

for end and their interponents lbe positioned to engage the rail at the same point, or they 4could be arranged symmetrically side by side, orp in various ways. Diiferent yarrangements of wiring and of timing contacts could bealso utilized, the principle of operation in all such cases remaining the saine.' l i From-all the foregoing it willbe understood that mechanism has. been provided `realizing the objects of `invention Land the advantages herein pointed out-togetherwith other objects and advantages. kIt will bey further understood that `changesimay be made from the illustrated and described form without departing, from the principles ofthe invention and without sacrificing its chief advantages.
